Abstract: Let  F[{x_1},...,{x_n}] be a polynomial ring with variables  {x_1},...,{x_n} over a field F. Suppose I is an ideal of  F[{x_1},...,{x_n}]. A subset  S \subset F[{x_1},...,{x_n}] is said to be a basis for I if it’s finitely generated by S. Fix a monomial order relation. We denote by LT(f) the leading term of  f \in F[{x_1},...,{x_n}] and LT(I) the set of all leading term of all elements in I. A subset  \lbrace {g_1},...,{g_t} \rbrace \subset F[{x_1},...,{x_n}] is said to be Grobner basis for I if \left \langle LT(I)  \right \rangle = \left \langle LT(g_1),...,LT(g_t) \right \rangle. In this paper we discussed the motivation of construction of the Grobner basis and a method to find the Grobner basis using Buchberger Algorithm.

Kata Kunci: Buchberger Algorithm, Grobner Basis, Ideal, Monomial Ordering, Polynomial Ring.
